WILLIAM S. BAIRD, OF DECATUR, ILLINOIS, ASSIGNOR TO BAIR-D CORN HUSKER CO., A CORPORATION OF SOUTH DAKOTA.

CORN-HARVESTER.

Specification of Letters Patent.

Patented Feb. 25, 1919.

Application led May 26, 1916. Serial No. 99,992.

To all 'whom t may concern:

Be it known that I, WILLIAM S. BAIRD, a resident of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Corn-I-Iarvesters, of which the following is a specilication.

This invention relates to improvements in corn harvesting machines and particularly t0 that type of machine disclosed in my prior Patents Nos. 892,208, June 30, 1908; 1,035,518, Aug. 13, 1912; 1,042,371, oet. 22, 1912; 1,077,963, Nov. 4, 1913; and 1,102,227, July 7, 1914..

An object of this invention is the provision of a plurality of pick-up chains and spiral reels and driving means for moving the chains faster than the speed of travel of the machine and the reels faster than the f' pick-up chains.

Another object of my invention is the provision of an improved form of husking roll.

Another object of my invention is the provion of an improved form of snapping ro Further objects include improvements in details of construction and arrangement whereby an eliiciently operating mechanism of the class described is provided.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be dened in the claims, reference being had to the accompanying draw-` ing forming a part hereof and which shows for the purpose of illustrative disclosure a preferred embodiment of my invention, it being expressly understood that various changes may be made in practice within the scope of the claims, without disgressing from my inventive idea.

In the drawings,

Figure 1 is a side'elevation of the part of a corn harvesting machine, parts being omitted so as to clearly disclose the arrangement of pick-up chains and reels and the driving means therefor.

Fig. 2 is a plan View of a portion of a pair of husking rolls.

Fig. 3 is a section taken on line 3 3 of Fig. 2.

Fig. 4 is a plan view of a pair of snapping rolls.

Fig. 5 is an enlarged fragmentary view thereof in plan.

Fig. 6 is a cross-section thereof, taken on line 6 6 of Fig. 5.

Referring first to Fig. 1 of the drawing, the numeral 1 designates the frame of the machine which is constructed and arranged to suitably support the mechanism. The supporting and driving wheels 2 have the gear 3 driving pinion 4 on shaft 5 on which is mounted bevel gear 6 meshing with small bevel gear 7 on upright shaft 8 having bevel gear 8 driving larger bevel gear 9 which in turn drives small gear 10 on the shaft 11 for reel 12, which is conical and has the spiral vane 13 thereon.

Another bevel gear 14 is secured to shaft 11 for driving bevel gear 15 on short upright shaft 16 having sprocket 17 at its lower end to drive the upper section of the upper pick-up chain 18. This chain extends downwardly and at its lower end engages sprocket 19 on upright shaft 20 which also has sprocket 21 thereon for driving the lower section 22 of the upper pick-up chain, the lower end of which engages idler sprocket 23. On the lower end of shaft 2O is secured sprocket 24 for driving the lower and short pick-up chain 25 which is also inclined downwardly parallel to section 22 and engages idler sprocket 26 at its lower end. On chains 22 and 25 I provide curved lingers 27 which are arranged at intervals of about live links and on chain 18, I arrange fingers 27 at intervals of about ten links. These chains are positioned over snapping bars 28 and snapping rolls 24 which are arranged as shown in my said prior patents, the snapping rolls however being shown in detail in Figs. 4, 5 and 6 of these drawings and described hereinafter.

These devices are arranged in pairs as Y disclosed in said prior patents so as to reg duce the desired result.

ceive the stalks and the gearing is so arranged that the chains move slightly faster than the machine and the spiral on the reels faster than the chains, so asv to pick up and raise fallen stalks to an upright position. The lower or bottom chain is advantageous for feeding the stalks that are close to the ground and also serves to knock the ears over onto the elevator or conveyer (not shown) and prevents them slipping down on the snapping bars.

Referring n ow to Figs. 2 and 3 of the drawing, 30 designates the frame for the husking rolls 3l and 32 which are driven from shaft 33 by means of the gearing shown. 31 i'sthe plain roller havingy a plurality of pins 34, while roller 32' has a spirally grooved surface, pins 34 being adapted to register with the groove, whereby the husks are grasped and fed along and through the husking rolls. As shown in Fig. 3, they rolls are preferably hollow.

In Figs. 4, 5 and 6, I show detail views of the snapping rolls 29, which are driven as shown, the shafts 35 having meshing gears 36 with long teeth,` so as to permit movement of the rolls relative to each other due to the movable b'oXes 37 being normally held together by springs 38. These rolls are provided with the spiral grooves 39 forming the recesses 40 and raised portions 41. The rolls are cut out or ygro'ovedrlongitudinally as at 42 so as to provide longitudinal engaging' portions or shoulders and spaces in alternation there-between. On thel raised portions and recesses I provide a plurality of cups orv depressions 43 preferably arranged in the cornersy of a rectangle orv square and in the center of each recess I provide a stud 44 and a corresponding depression in the raised portion, which cooperates with the stud when the rolls are rotated. The studs 44 preferably taper slightly.

In operation, the rolls being driven in opposite directions, will feed the stalks rearwardly and downwardly due to the engagement of the studs and depressions therewith. The shoulders provided byv the cut-out portions or grooves 42 form effective means to grip and grasp the stalks to force them through between'the rolls to snap the ears therefrom. Their yielding mounting permits their 'separation in case of necessity.

This construction coperates to* provide a rne'ehanism'w'hich operates effectively to pro- What I claim A 1. In a corn harvesting machine of the kind described and in combination, rotatable reels provided with spiral vanes thereon, a pair ei piek-up ehains arranged below said reels, and means for driving said reelsl and chains at speeds whereby the reels will lift and move' the upper part ef the stalks' rearward at greater speed than the portion of the stalk engaged by the chains.

2. In a corn harvester of the kind described and in combination, a pair of reels, pickup chains arranged below said reels, and means for driving said reels and said chains at speeds whereby fallen stalks engaged by the reels and chains will be straightened up simultaneously with the rearward feeding of the same and the upper part of the stalk fed rearwardly with greater speed than the feeding of thevlower part due to the travel of the harvester.

3. In acorn harvester of the kind described and in combination, reels arranged on inclined axes, pick-up chains arranged below and paralleling said reels, and means dependent on the travel of the vehicle for driving said chains and reels whereby the portion of the stalk engaged by the chains is fed rearwardly at greater speed than the speed of the harvester and the part of the stock engaged by the wheels is fed rearwardly at greater speedk than the part of the stalk engaged by the chains, and the stalk will be straightened up simultaneously with the rearward feeding of the same in the harvester due to the forward travel of the harvester.

4. In a corn harvester of the kind described and in combination,v a pair of reels, a set of pick-up chains below said reels and provided with fingers thereon, a second set of pick-up cha-insl extending rearwardly from the first set of chains and provided with fingers thereon, the fingers' on the second set being spaced apart greaterv distances than the fingers on the first set, and a third pick-up chain located below the first mentioned section and movable therewith whereby the second and third sets will advance the stalk uniformly at different points.
